Maurice Biais was a French painter, draughtsman and illustrator.

From 1899, he designs furniture for La Maison Moderne, an art gallery founded by Julius Meier-Graefe. He designed leather goods for the shop, as well.

He married Jane Avril in 1911. They lived in Jouy-en-Josas until his death in 1926, which has been attributed to his having been gassed during World War I.
